They don't care about you. - Freight Conductor Union Pacific Employee Review

After you are hired, the company and managers are constantly trying to find ways to either fire you, or get rid of your job. Currently, it takes about 10+ years of seniority to even be close to working full time. Furloughs are common, and can sometimes last for years. They expect you to be ready and available to work 24/7 all year, including holidays, but their attendance policy has zero leeway, and taking off more than 3 days within a 90 day period will get you fired.
